Riverine flooding information for the South Esk River, Macquarie River and Back Creek

Flood map for Latrobe township and surrounds, including levee protected areas

若要更詳細地查看地圖,, 查看塔斯馬尼亞策略性洪水圖.

Longford can have riverine flooding from the South Esk River, Macquarie River and Back Creek. The levee system was constructed to protect Longford and mitigate against rare flooding events of the South Esk River.

The map shows the expected Major Flood levels in the Longford region. This level of event has about a 1% chance of happening any year (1% Annual Exceedance Probability (AEP). You are likely to experience a flood of this size in your lifetime.

A 1% AEP event is the limit of flood mitigation provided by the Longford levee system. Above this level there will start to be flooding within the levee protected area.
In the event of levee gate closure at Tannery Road access to the north is closed, and some streets off Wellington Street to the east. This will include the installation of some temporary levee structures. An alternative flood access plan will become activated during a major flooding event.

During a Major flooding event there are three alternative routes that can be used according to the height of the floodwaters, and closure status of the levees:

  • Route 1 (Green)Before closure of Illawarra Road vehicles can travel out of Longford via Wilmores Lane (Opposite Austral Bricks), turn right onto Bishopsbourne Road and turn right onto Illawarra road towards Perth, or left to the Bass Highway. This route may be closed considerably earlier than the flooding risk by Tasmania Police.
  • Route 2 (Purple) – When Illawarra Road to the east of the Longford town entrance becomes closed, vehicles can travel out via Wilmores Lane, turn right onto Bishopsbourne Road and turn left onto Illawarra Road and travel north to the Bass Highway.
  • Route 3 (Orange) – When Illawarra Road is closed to the east and west of the town entrance, vehicles can travel out via Wilmores Lane, turn right onto Bishopsbourne Road and continue along the road to Carrick (Meander Valley Road), and then onto to the Bass Highway.

Even if your home is not inundated, you may be isolated for several days. You should have supplies for up to three days and be prepared for power and telecommunications outages. Note if you are isolated, you may not be able to access medical or other help if needed.

Bureau of Meteorology (BoM) Forecasts, Warnings, and Observations

BoM issues a Flood Watch when predicted weather might cause floods in one or two days. A Flood Watch may

  • be for a specific area such as Longford.
  • be for the South Esk River, or Macquarie River.
  • be generalised such as for the Central North forecast area.

BoM issues a Severe Weather Warning for very heavy rain that may lead to flash floodingwhenever this weather is occurring or is expected in an area. The amount of time between the warning and the arrival of the heavy rain can vary from an hour to 24 hours or sometimes more.

BoM issues Flood Warnings with specific flood heightsfor the South Esk River at Longford gauging site with warnings of flood heights. Flood warnings can be issued for Minor (3.5m), Moderate (5.0m) and Major (7.0m) flood levels.

No two floods are the same. Floods like the one shown in the map or worse will occur again.

If you live in a low-lying area you may be at risk of flooding. Even if your home is safe, you may need to detour around flooded areas. Never drive through or enter flood waters.

Knowing what to do can save your life and help protect your property. Preparing a Home Emergency Plan is one of the best ways to prepare.

Include weather and rainfall triggers for action in your Home Emergency Plan.

了解你的風險,做好準備,盡可能降低風險,與他人聯繫,保持警惕並安全行動。.

洪水之前

1. 認識你的風險

塔斯馬尼亞經常發生洪水,可能造成廣泛且嚴重的損害。在過去 200 年裡,塔斯馬尼亞有 78 人死於與洪水相關的事件。本指南旨在幫助您了解您所在地區的洪水風險。.

2. 準備您的家戶

制定包含風暴和洪水應變計畫

思考一下在風暴或洪水來襲時你會怎麼做,意味著你準備得更充分,每個人都會更安全。制定一個家庭中的每個人都理解的緊急計畫。有檢查表可以幫助你思考你的計畫——請參閱 為緊急情況做好準備 – 為個人和家庭準備應急措施的指南。. 
定期檢查您的計劃,並讓家中的每個人都設想一次可能影響您家的洪水情況來進行測試。.

準備一個緊急救生包

準備好了

  • 電池供電的收音機和手電筒,備用電池
  • 重要資訊,例如您的緊急應變計畫
  • 緊急電話號碼列表
  • 食物和水
  • 急救箱
  • 橡膠手套或堅固的皮革手套

需要時打包

  • 暖和的衣服、結實的鞋子或靴子
  • 藥品、眼鏡或其他必需品
  • 手機和充電器
  • 寵物食品和他們需要的任何其他東西
  • 照片和特別紀念品
  • 重要文件,例如
    • 保險文件
    • 護照與
    • 出生證明

定期測試收音機和手電筒的電池。.

3. 在可能的情況下,降低您遭受洪水侵襲的風險

  • 在購買、維護或開發房地產時,請考慮風暴、洪水和其他災害。.
  • 修剪或移除您家中、商家或您家附近有電力線的樹木和樹枝。.
  • 保持您的排水溝和排水管暢通。.

4. 與他人建立聯繫

認識你的鄰居並參與你的社區。一個緊密的社區,在緊急情況下更安全、更有韌性,並有助於每個人在事後更好地恢復。檢查家人和鄰居是否安全,並了解正在發生的事情。.

期間

5. Keep up to date

隨時留意周遭狀況。定期查看天氣預報、觀測數據和警報。. 

6. Act Safe

  • 監督兒童.
  • 為可能的停電、停水或斷網做好準備。.
  • 檢查您的緊急救助包是否已準備就緒。.
  • 切勿靠近淹水區域,例如排水溝。. 永不 在洪水中有行走、玩耍、骑行或开车。你無法確定水下有什麼,或水有多深、流速有多快。20公分的湍急的洪水就很容易將人沖走並淹死。洪水可能很危險。.

您的房屋可能發生淹水時

  • 將家居物品放在高處,以盡量減少潛在損壞。.
  • 如果安全的話,請關閉水電和瓦斯。. 
  • 一種防止污水倒灌回屋內的好方法是將沙包放入塑膠袋中,然後用它們來堵塞馬桶、蓋住排水孔和水槽。.
  • 趁你還能安全脫困時趕快離開。.

如果你需要疏散

  • 請遵循 SES / 塔斯馬尼亞警方的建議。.  
  • 帶上你的緊急求生包。. 
  • 前往朋友或家人較安全的地方,或前往疏散中心。. 
  • 讓別人知道你去了哪裡。.

照顧好你的動物

在緊急情況下,您有責任照顧您的動物。如果您有寵物和其他動物,在洪水或其他緊急情況下,疏散的時間會更長。在洪水可能上漲之前,請及時將牲畜移離易受洪水影響的地區。更多資訊請參閱

請避免在風暴期間和風暴之後旅行

  • 不要去觀光。觀光客會延誤緊急服務並造成事故。.
  • 注意危險,例如
    • 路面积水
    • 損壞的電力線
    • 山崩
    • 損壞的道路
    • 倒下的樹木或屋頂鐵片。.
  • 切勿駕車通過淹水區域。洪水中的大多數死亡和救援事件都與駕車通過淹水區域有關。.
  • 緩慢行駛,並在不受洪水影響的道路上打開頭燈。.

之後

  • 請持續收聽 ABC 地方電台的最新消息、道路重新開放、社區會議等資訊。.
  • 如果您離開家,請勿在聯邦緊急事務局 (SES) 或塔斯馬尼亞警方告知您安全之前回家。.
  • 注意道路上的危險,例如路面上的泥沙或碎屑、道路/橋樑損壞以及正在進行清理和修復工作的工人。.

如果您的房屋已受損

  • 在檢查損壞時,請待在地面。小心掉落的樹木、碎玻璃、鬆動的屋頂或其它危險物品。.
  • 穿著堅固的靴子、手套和防護服。. 
  • 請使用手電筒,切勿在受洪水影響的建築物內使用火柴或蠟燭。. 
  • 將所有飲用水煮沸,直到被告知自來水再次安全為止。.
  • 在經註冊電工或燃氣技師測試安全之前,請勿開啟電力或燃氣。.
  • 如果您的房屋受損,需要暫時住在其他地方,請攜帶您的緊急應變包和寵物一同前往。
  • 如安全,請拍攝任何損壞的照片,並聯繫您的保險公司。.
  • 監督兒童.
  • 檢查鄰居是否安好。.

免責聲明

The maps show potential flooding risks from consistent levels of rainfall across catchments, such as a 1% Annual Exceedance Probability (AEP).  In flooding events, rainfall is likely to be more inconsistent across a catchment, so these flood maps should be considered indicative only.  The mapped areas of flood risk show higher probability of inundation. Other areas have lower probability of flooding, but in severe and rare events (rarer than 1%AEP), other lower areas may be also at risk of inundation.
